Suppose you wrote a program like HW9's rpn.c, except it was to read the input from a file opened with fopen instead of from stdin. Assume that code contains the line fscanf(f, "%s", buffer), where f was that opened file.  Based on this information, your code: A. Has a buffer overrun vulnerability B. Has a use-after-free vulnerability C. Has an uninitialized memory vulnerability D. Will cause a segmentation fault

Write a complete program that uses an ifstream object to read integers from a file called numbers.txt, and an ofstream object to write into a file called evens.txt.Your program should have loop that reads each integer from the input file, then writes it into the output file if it is an even number. Write each even number in na separate line.Make sure to close both files before your program terminates.

You'll write a C++ program to demonstrate thread synchronization. Your main function should first create an empty file called *sync.txt*. Then it will create two separate threads: *Thread-A* and *Thread-B*. Both threads will open *sync.txt* and write to it simultaneously.   *Thread-A* will write the numbers 0 through 9, a total of fifty-thousand times in nested `for` loops, then exit. In other words, print the numbers 0 through 9 over and over again, with each run on a separate line, for 50,000 lines. Here's an example of one such line: ```text 0 1 2 3 4 5 6 7 8 9 ```   Somewhat similarly, *Thread-B* will write the letters A through Z fifty-thousand times in nested `for` loops, then exit. In other words, print the letters A through Z over and over again, with each run on a separate line, for 50,000 lines. Here's an example of one such line:   ```text A B C D E F G H I J K L M N O P Q R S T U V W X Y Z ```   Do not write each line as one long string. You must write each character to the…

Write a high-security program in C that reads positive integers from a file "/challenge/numbers.txt" in the same directory as the program and outputs the biggest and smallest number.        Input (from numbers.txt):            100            45            12            0            42            922            2        Output:            922            0
